  • We have done the first one…And today we are completing the second part of this CAP grantThe third will occur as we begin to put together a final reportThe forth will begin once we have the final report in hand and are ready to chase new money.
  • What brings us together today is number 2 of the CAP Grant: to run a workshop and solicit feedback on the surveyMore importantly, this is part of our process to begin updating of the NSDI framework data layers in the I-PlanDue to time and money, we are focusing on imagery which was part of the Landcover/Land Use themeIt is the largest and most expensive to acquire and has a plethora of data requirements, so the group selected this to begin withIf we can outline requirements and issues for this theme, we will have tackled most of the elements required by the othersWe can then build upon this
  • Want feedback and ideas (stakeholder engagement)Want to generate as many ideas as possible (brain storm)There are no dumb ideas or issues (don’t take anything personal, we are talking ideas)Time may force us to move quicklyRelated issues that require more time than we have today will be noted for follow up (i.e., “parking lot”)
  • We have a lot to cover, so if you need to get up and grab a cup of coffee or use the restroom, please feel free to do so.The bathrooms are located…………………….If you could, please silence your phone or put it on vibrate so as not to disturb others.
  • Generally….
  • Not surprising, the highest overall job function was planning with 66.7%then natural resource mapping, digitization, each with 63%,and then environmental monitoring with 49%, and site design with 37%.
  • The correlation between imagery function and use with planning and design, environmental management, and disaster analysis across affiliations provides good support for future imagery funding requests.
  • Natural color wins the day with 84% of the vote.
  • 6 in wins the day with 37% with 1ft and under totaling nearly 60% of total respondents.
  • Here is the break down by affiliation.What would 6 inch imagery be used for?What would 1 inch imagery be used for?
  • Submeter by far the most used but subfoot being the ideal for engineering and infrastructure with 1-5 meters being used for natural resources
  • Digital color in 3 or 4 bands dominates in all sectors, especially in the private sector.Hyperspectral still obviously fills an important niche showing up evenly in the academic, federal, state, and private sectors.
  • Mention – reality – large files delivered via portable storageCon – This leads to “sneaker netting” the data from person to personYou need to know WHO has the data and HOW to get it
  • Get more feedback from participants on thisDesire is “every year”? Or is that actually how often they purchase?What’s the reality?Parking lot: Become a NAIP state
  • Note the high number of private consultants that buy every six months and every year….Confirm that this is because the work is project based?
  • 73% of respondents by 0 to $25K a year in imagery annually.Show of hands…how many of you answered 0-25K when 0 was actually the reality?Conservative best case scenario is that the folks participating in this exercise are spending about $3,000,000Worse case is you are spending at least $1,825,000.My gut says it is more like $5 million if you count DoD and the engineering firms that did not participate in this exercise.
  • Here is the break down of average annual expenditures by organization type.Federal dominates higher end spending. I wanted some feedback here. Is it that you have larger areas to cover? You are better funded?
  • Many are members of the Ikonos Consortium, which now has most of the state covered.The concept built on the first consortium which brought together 26 organizations to band together to buy SPOT imagery which at the time was 10m panchromatic and 20m multispectral. We took that example to Space Imaging to convince them that selling to a public/private consortium was the only way they would get mass sales in Hawaii and it worked. It took care of licensing issues and provided a kind of snow balling data sharing scheme in which all those who joined got to pick their area of interest and then each member got each others datasets until we could “piece” together the whole state.Space Imaging told me this was the first consortium of its kind. A successful model.
  • Why obliqueLarge pool of money to support E911Pictometry became the front runner because of 3D representation or realityChanging face of “GIS”
  • Shows need for storing data in a variety of datums
  • UTM Zone 4 is the most widely used coordinate system
  • Not surprisingly, this slide shows that those who work statewide mostly use UTM Zone 4 with some Zone 5, with those working a single county using State Plane. Typically you see this split between natural resource organizations who use UTM meters and public works, who predominately use State Plane and feet.
  • The last 3 slides shows the need for either storing or facilitating the delivery of data in a variety of coordinate system, datum, and unit combinations.
  • Need feedback on the meaning of partial
  • ERDAS is the front runner for image processing, with ENVI close behind. Very much to be expected.But ESRI dominants in this particular question. What do you suppose the reason for that is?Are folks using the Image Analyst extension?To me this high percentage supports the other findings, that the majority of users are using imagery as a background layer, or for overlay analysis to support change detection, feature extraction, or attribution. Most are not doing image processing.
  • Not surprising is that the Federal government is using ERDAS quite a bit. It is top of the line so a bit pricey and it is used a lot for natural resource management in the form of vegetation mapping, restoration progress, change detection, etc.Interesting spread around ESRI showing that ESRI software is obviously vital to those polled.
  • Question aimed at understanding what other kind of raster data might be out there.
  • Here is the breakdown by affiliation.What is being scanned?What resources should be scanned?
  • What would be the reason for 62% of the respondents to not be making the data available?Security?Data senstivity?Don’t have the resources to make them available?
  • The take home message here is that imagery is a vital component of a GIS system providing the basis on which other data is derived to support wise decision making.
  • Maybe show current fundingUSGS $200KUSDA $190KNPSUSFWSDOTDLNRDHSHIARNGOthersPartnerships and cost sharing is the best opportunity for large scale acquisitions. SPOT Image, Ikonos consortium.Nextmap – case in point, what can happen when you don’t go in “together”Storage – exponential increase in storage need with each new platform. Sharing - Need to know WHO has the data…sneaker net problem. In order to share, you need to organize and “buy” together so you overcome licensing issues.
  • We researched many of the web sites and compiled a matrix of key functionalty that we started to see in common to all. This will be a part of the final report.
  • Calls itself a one stop. Seems to be hosted by Dept of Land and Natural Resources.Easy to find their data. A bit disjointed, have to search a bit to find data, may be a delay in request and delivery of data.May not be the accuracy you want. Hard to tell what scale you are getting. Datasets seem very coarse.Does have lots of options for ftp, cd, existing map library, or online mapping, but might link to different agencies.No easy way to find stuff geographically or by metadata. Does link to USGS hosted clearing house which primarily has Federal datasets but does have 3 municipal sets.The Alaska State Geospatial Data Clearinghouse links back to the page you just came from.
  • Called a portal, minimalist site.ArcExplorer site but very old user interface style. Slow, minimalist. No links to other sites for data. Can’t find downloadable data. Doesn’t have info on whether it is a GIS council or who might be involed.There is a metadata catalog, in which all recs are classified as “Document” (as opposed to live map, downloadable data, etc.)
  • Clearly defines audience as GIS professional.Note the Twitter and Facebook feeds. Great for communicating and following improvements, asking others for advice, giving advice.Has map viewer.Map viewer is nice looking, fast, Silverlight/Flex.Very nice shaded relief topo maps and aerial imagery.They spell out their services really well. Have web services, web feature services, web mapping services, apps, etc.FTP downloadsDL downloads using geographic queries like watershed, city, county, etc., with which to request, clip, and zip.A Blog is a very nice feature as is a Tutorial.There administrative structure is really nice with a State GIO, State GIS Board (used to be Land Information System), State GIS department, and technical advisory committees. Recognized and set up by Gov. Huckabee
  • Uses metadata search and/or geographic or key word searches.The Search for Data link searches the metadata repository for data or services maintained by state, local and federal agencies or the inventory of geospatial data among local agencies. But…if you don’t publish your data here…one’s searches come up empty. Can be frustrating to try and track down data, though.Searches often return very few records. Case in point, the search for arapaho data, any data, any time are selected, yet only returns one record. Same thing occurs using the graphic selection tool. I selected Boulder because I know they have a robust GIS system.Why do you think I didn’t get a return on data? Success relies on user participation which requires agencies or individuals to register, fill out metadata, and publish one’s data. It also may be that the data hasn’t been updated since 2006, or maybe its just the website verbiage that hasn’t been updated (and it still says based on inventory from 2006). It can also be that a certain city or county just doesn’t have any data…so searches come up blank. Hard to tell. But the frustration means that people would tire of the site and revert back to making phone calls to friends in the biz or sending out “help” emails to the list serve.The site begins to be quite effective when you click on Direct Links to Colorado Data. Now you can see who has “downloadable” data. By linking directly to different departments and sites, you get the latest data. Only problem is, you have to navigate through many different sites which are all done differently.Governor created a State GIO position and there is an active GIS counsel and user base. ESRI, Trimble, and a host of other GIS firms abound in the State as do avid GIS departments in state and private universities.
  • For many of these sites, it’s too hard to find the data – e.g., here it’s under “Resources”;This links you to the University of Connecticut, specifically their University Library’s Map and Geographic Information Center (called MAGIC).GIS and map data is treated like a reference material. Something to be stored and retrived digitally by people who need to find and use the data.Very nice site. Easily searchable via icons that show data type, scale, year, source, metadata, coor sys and datum, shape, kml, or preview in Google Maps including nice attribute viewer.Utilize a blog, facebook, twitter accounts.Uses Flicker to share raster maps from the library.Very nice Apple-like browsing of historic raster maps.Also has instructions on making map mashups and adding WMS services to ArcGIS. Very proactive.Much of their data comes in 1:24000 Scale from the CT Dept of Environmental Protection, Trinity College, and US Census.
  • Currently the web site is inward focused to GIS usersWe want to increase user ship to benefit the community
  • Given all this great discussion and examples, it is your turn to provide us anonymous feedback by commenting, choosing, or ranking the importance of each data requirement.
